Constructor Detail

ThreadPoolThread

public ThreadPoolThread(ThreadPool pool,
                        java.lang.ThreadGroup threadGroup,
                        java.lang.String name)

Create a thread belonging to a particular ThreadPool.

Parameters:

pool - the Threadpool this thread belongs to

threadGroup - the ThreadGroup this thread belongs to

name - the name of this thread

Method Detail

run

public void run()

Loop forever, waiting for work to do.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

isBusy

boolean isBusy()

Return whether this thread is currently busy. Of course in a threading environment, this condition can change at any time, so the result should only be considered indicative.

Returns:

shutdown

void shutdown()

Set the shutdown flag, and stop the thread the next time through the loop. This does not call pool.notify, so it's up to the caller to do that.
